How To Do The Maintenance Work Of Roller Mill


The roller mill is mainly used for the milling and processing of calcite, limestone, marble, barite, bentonite and other minerals. The Star equipment produced by Shanghai Zenith Mineral Co., Ltd. is the MTW Euro-type Trapezium mill. The mill can process a variety of stone materials, and the fineness can be adjusted freely between 30-400mesh, so it is a machine with multiple functions.

First of all, during the use of the mill, a fixed person should be responsible for the supervision, and the operator must have a certain technical level. Before the installation of the mill, the operating personnel must be technically trained to understand the principle and performance of the mill and be familiar with the operation Procedures. In order to make the mill work normally, the equipment "maintenance and safe operation system" should be formulated to ensure the long-term safe operation of the mill, and the necessary maintenance tools and grease accessories should be provided.

Secondly, after the mill has been used for a period of time, it should be overhauled. At the same time, the wearing parts such as the roller, ring and shovel should be replaced. The connecting bolt and nut plug of the roller device should be carefully checked before and after use to see if there is any looseness, and whether to add enough lubricating grease. When the roller device is used for more than 500 hours, it is required to check the roller condition, and the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced. The refueling tool can be manually refueled or a grease gun.
